Yes, Simpilots payware modules are compatible with the latest beta and it is a full install but you can just upgrade.
Go here and download the full version of 2.1.934. This is not the beta
I am but you have to be carefully because it's beta for a reason. A lot of people don't run beta's on a prod site because you could have a ton of issues. However, I have a prod and a dev site and I do all my testing on the dev site. If everything checks out I upgrade my prod site over. So, you can do this but you need to be very careful.
